Guys
Due to their shallow depth I'm considering building a pair of these for near field desktop use.

Now these look to employ a pair of Tang Band W4-1320SIF. But for the life of me I can't find out the manufacturers recommended enclosure volume. Can anyone help me with this? Also, should they be ported or sealed?

Also, as a design challenge I was considering concrete as a material, or 19mm ply sandwiched together. Anyone care to comment on the material choice?

Now I've considered the mHonkens and have built three of Dave's designs which I love. This time I'm looking for something visually different for my computer speakers. More of a design statement, but with solid audio performance.

I don't see much point in using anything beyond PVC pipe, or even thick cardboard tube for a speaker like this.

My 1st inclination would have the driver in the "box" you point to as a 3"/

I have a similar speaker that uses a standard PVC adapter with a fitted wooden ring with 4" PVC pipe that perfectly fits both an Alpair 5 and the big buck 3" Scan Speak 10F (only 2 drivers i have tried in it.

Thanks Dave.
I see the volume of your tube speaker are significantly larger than that of the "Well Rounded" design. Part of their appeal to me was their shallow depth. In that they would sit either side of my laptop without taking too much space.

What drivers do you think would suit such a small enclosure?

without hearing the Well Rounded, it'd be hard to say if the drivers used therein are achieving anywhere near their full potential - those are pretty teeny enclosures for sure

While a friendly debate could ensue if addressing the technical merits (or not) of using concrete or any high mass material for moveable speaker enclosures of any design (can you read between the lines on my thoughts on the subject? ), it's probably easier for most DIY hacks to make a decent looking enclosure folks from more conventional materials (wood, PVC pipe* / cardboard tubes, etc) than with concrete / diamond cored basalt - you name it.

So more than anything, I'd say it's the pain in the but-tocks factor that keeps more folks from trying it.

My cab is just an example, in this case a mid-TL, if i was using it FR i'd optimize the volume for sealed ot Vented box.

Alpair 6.2 (either) or FF85wk would be my 1st choice. Your pipe would need 2.5 litre. The 6M and FF85 can get away with less volume (down to say 1.5 litre -- in the case of the 6M the vent becomes so large that you might as well build the 2.5.
